As an enhancement to the conventional SFP interface defined in SFF-8074i, the AFBR-57R6APZ is compliant to SFF-8472 (digital diagnostic interface for optical transceivers). Using the 2-wire serial interface defined in the SFF-8472 MSA, the AFBR-57R6APZ provides real time temperature, supply voltage, laser bias current, laser average output power and received input power. This information is in addition to conventional SFP base data. The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Transmitter Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS).
Installation The AFBR-57R6APZ can be installed in any SFF-8074i compliant Small Form Pluggable (SFP) port regardless of host equipment operating status. The AFBR-57R6APZ is hot-pluggable, allowing the module to be installed while the host system is operating and on-line. Upon insertion, the transceiver housing makes initial contact with the host board SFP cage, mitigating potential damage due to Electro-Static Discharge (ESD).

Digital Diagnostic Interface and Serial Identification
Fault Isolation
The 2-wire serial interface is based on ATMEL AT24C01A series EEPROM protocol and signaling detail. Conventional EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8074i. New digital diagnostic information, bytes 0-255 at memory address 0xA2, is compliant to SFF-8472. The new diagnostic information provides the opportunity for Predictive Failure Identification, Compliance Prediction, Fault Isolation and Component Monitoring.
The fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime. For optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an installation. AFBR-57R6APZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can be used to assess local transceiver current operating conditions. In addition, status flags Tx_Disable and Rx Loss of Signal (LOS) are mirrored in memory and available via the two-wire serial interface.
The I2C accessible memory page address 0xB0 is used internally by SFP for the test and diagnostic purposes and it is reserved.
Predictive Failure Identification The AFBR-57R6APZ predictive failure feature allows a host to identify potential link problems before system performance is impacted. Prior identification of link problems enables a host to service an application via “fail over” to a redundant link or replace a suspect device, maintaining system uptime in the process. For applications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics associated with observing laser degradation and predicting failure: average laser bias current (Tx_Bias) and average laser optical power (Tx_Power).
Compliance Prediction Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-57R6APZ devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. Received optical power is also available to assess compliance of a cable plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission.

Component Monitoring Component evaluation is a more casual use of the AFBR57R6APZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power. Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or field qualification. For example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, PCI cards and systems.

Transmitter Section
Transmit Fault (Tx_Fault)
The transmitter section includes the Transmitter Optical SubAssembly (TOSA) and laser driver circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom IC which uses the incoming differential high speed logic signal to modulate the laser diode driver current. This Tx laser driver circuit regulates the optical power at a constant level provided the incoming data pattern is dc balanced (8B/10B code, for example).
A catastrophic laser fault will activate the transmitter signal, TX_FAULT, and disable the laser. This signal is an open collector output (pull-up required on the host board). A low signal indicates normal laser operation and a high signal indicates a fault. The TX_FAULT will be latched high when a laser fault occurs and is cleared by toggling the TX_DISABLE input or power cycling the transceiver. The transmitter fault condition can also be monitored via the two-wire serial interface (address A2, byte 110, bit 2).
Transmit Disable (Tx_Disable)
The AFBR-57R6APZ provides Class 1 (single fault tolerant) eye safety by design and has been tested for compliance with the requirements listed in Table 1. The eye safety circuit continuously monitors the optical output power level and will disable the transmitter upon detecting an unsafe condition beyond the scope of Class 1 certification. Such unsafe conditions can be due to inputs from the host board (Vcc fluctuation, unbalanced code) or a fault within the transceiver.
The AFBR-57R6APZ accepts a TTL and CMOS compatible transmit disable control signal input (pin 3) which shuts down the transmitter optical output. A high signal implements this function while a low signal allows normal transceiver operation. In the event of a fault (e.g. eye safety circuit activated), cycling this control signal resets the module as depicted in Figure 4. An internal pull up resistor disables the transceiver transmitter until the host pulls the input low. Host systems should allow a 10 ms interval between successive assertions of this control signal. Tx_Disable can also be asserted via the two-wire serial interface (address A2h, byte 110, bit 6) and monitored (address A2h, byte 110, bit 7). The contents of A2h, byte 110, bit 6 are logic OR’d with hardware Tx_Disable (pin 3) to control transmitter operation. 3
Eye Safety Circuit
Receiver Section The receiver section includes the Receiver Optical SubAssembly (ROSA) and the amplification/quantization circuitry. The ROSA, containing a PIN photodiode and custom transimpedance amplifier, is located at the optical interface and mates with the LC optical connector. The ROSA output is fed to a custom IC that provides postamplification and quantization. Fibre Channel Rate Select (Rate_Select) The AFBR-57R6APZ transceiver contains a parametric optimiza-tion circuit to insure compliant performance for 1.0625 Gb/s, 2.125 Gb/s and 4.25 Gb/s data rates. When Rate_Select (pin 7) is asserted, the transceiver receiver bandwidth is optimized for 4.25G/2.125G performance as defined in document SFF-8079 Section 5.1 (currently on Draft 1.7) and ANSI FC-PI-2. When deasserted (or open), performance is optimized for 2.125G/1.065G performance per SFF-8074i and SFF-8079. Rate_Select can also be asserted via the two-wire serial interface (address A2h, byte 110, bit 3) and monitored (address A2h, byte 110, bit 4). The contents of A2h, byte 110, bit 3 are logic OR’d with hardware Rate_Select (pin 7) to control transmitter operation.
Receiver Loss of Signal (Rx_LOS) The post-amplification IC also includes transition detection circuitry which monitors the ac level of incoming optical signals and provides a TTL/CMOS compatible status signal to the host (pin 8). An adequate optical input results in a low Rx_LOS output while a high Rx_LOS output indicates an unusable optical input. The Rx_LOS thresholds are factory set so that a high output indicates a definite optical fault has occurred. Rx_LOS can also be monitored via the two-wire serial interface (address A2h, byte 110, bit 1).
Functional Data I/O The AFBR-57R6APZ interfaces with the host circuit board through twenty I/O pins (SFP electrical connector) identified by function in Table 2. The board layout for this interface is depicted in Figure 6. The AFBR-57R6APZ high speed transmit and receive interfaces require SFP MSA compliant signal lines on the host board. To simplify board requirements, biasing resistors and ac coupling capacitors are incorporated into the SFP transceiver module (per SFF-8074i) and hence are not required on the host board. The Tx_Disable, Tx_ Fault, Rx_LOS, and Rate_Select lines require TTL lines on the host board (per SFF-8074i) if used. If an application chooses not to take advantage of the functionality of these pins, care must be taken to ground Tx_Disable (for normal operation). 4
Figure 2 depicts the recommended interface circuit to link the AFBR-57R6APZ to supporting physical layer ICs. Timing for MSA compliant control signals implemented in the transceiver are listed in Figure 4.
Application Support An Evaluation Kit and Reference Designs are available to assist in evaluation of the AFBR-57R6APZ. Please contact your local Field Sales representative for availability and ordering details.
Caution There are no user serviceable parts nor maintenance requirements for the AFBR-57R6APZ. All mechanical adjustments are made at the factory prior to shipment. Tampering with, modifying, misusing or improperly handling the AFBR-57R6APZ will void the product warranty. It may also result in improper operation and possibly overstress the laser source. Performance degradation or device failure may result. Connection of the AFBR57R6APZ to a light source not compliant with ANSI FC-PI or IEEE 802.3 specifications, operating above maximum operating conditions or in a manner inconsistent with it’s design and function may result in exposure to hazardous light radiation and may constitute an act of modifying or manufacturing a laser product. Persons performing such an act are required by law to re-certify and re-identify the laser product under the provisions of U.S. 21 CFR (Subchapter J) and TUV.

Regulatory Compliance The AFBR-57R6APZ complies with all applicable laws and regulations as detailed in Table 1. Certification level is dependent on the overall configuration of the host equipment. The transceiver performance is offered as a figure of merit to assist the designer.
Electrostatic Discharge (ESD)
Electromagnetic Interference (EMI)
The AFBR-57R6APZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 1. In the normal handling and operation of optical transceivers, ESD is of concern in two circumstances.
Equipment incorporating gigabit transceivers is typically subject to regulation by the FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. The AFBR-57R6APZ’s compliance to these standards is detailed in Table 1. The metal housing and shielded design of the AFBR-57R6APZ minimizes the EMI challenge facing the equipment designer.
The first case is during handling of the transceiver prior to insertion into an SFP compliant cage. To protect the device, it’s important to use normal ESD handling precautions. These include use of grounded wrist straps, work-benches and floor wherever a transceiver is handled. The second case to consider is static discharges to the exterior of the host equipment chassis after installation. If the optical interface is exposed to the exterior of host equipment cabinet, the transceiver may be subject to system level ESD requirements.
EMI Immunity (Susceptibility) Due to its shielded design, the EMI immunity of the AFBR-57R6APZ exceeds typical industry standards.
Flammability The AFBR-57R6APZ optical transceiver is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic.

Notes: 1. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7 k – 10 kΩ resistor on the host board. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. 2. TX_DISABLE is an input that is used to shut down the transmitter optical output. It is internally pulled up (within the transceiver) with a 6.8 kΩ resistor. Low (0 – 0.8 V ): Transmitter on Between (0.8 V and 2.0 V ): Undefined High (2.0 – Vcc max) or OPEN: Transmitter Disabled 3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 kΩ resistor on the host board. Mod-Def 0 is grounded by the module to indicate the module is present Mod-Def 1 is serial clock line (SCL) of two wire serial interface Mod-Def 2 is serial data line (SDA) of two wire serial interface 4. RATE_SELECT is an input used to control transceiver compatiility for multiple rates. It is internally pulled down with a >30 kΩ resistor. Low (0 - 0.8 V) or OPEN: Low Bit Rate Compatibility per SFF-8074i (1.0625 Gb/s and 2.125 Gb/s per SFF-8079) Between (0.8 V and 2.0 V) Undefined per SFF-8074i High (2.0 – Vcc max): High Bit Rate Compatibility per SFF-8074i (2.125 Gb/s and 4.25 Gb/s per SFF-8079) 5. RX_LOS (Rx Loss of Signal) is an open collector/drain output that must be pulled up with a 4.7 k – 10 kΩ resistor on the host board. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. 6. RD-/+ designate the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω differential at the host SERDES input. AC coupling is done inside the transceiver and is not required on the host board. The voltage swing on these lines will be between 600 and 1600 mV differential (300 – 800 mV single ended) when properly terminated. 7. VccR and VccT are the receiver and transmitter power supplies. They are defined at the SFP connector pin. The maximum supply current is 300 mA and the associated in-rush current will typically be no more than 30 mA above steady state after 2 microseconds. 8. TD-/+ designate the differential transmitter inputs. They are AC coupled differential lines with 100 Ω differential termination inside the module. The AC coupling is done inside the module and is not required on the host board. The inputs will accept differential swings of 400 – 2400 mV (200 – 1200 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 – 600 mV single ended) be used for best EMI performance.

Max Pout is the lesser of Class 1 safety limits (CDRH and EN 60825) or receiver power, max. 6. Into 50/125 µm (0.2 NA) multi-mode optical fiber. 7. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern. Contributed TJ is the sum of contributed RJ and contributed DJ. Contributed RJ is calculated for 1x10-12 BER by multiplying the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per FC-PI (Table 13 - MM jitter output, note 1), the actual contributed RJ is allowed to increase above its limit if the actual contributed DJ decreases below its limits, as long as the component output DJ and TJ remain within their specified FC-PI maximum limits with the worst case specified component jitter input.
